Activity Date: 2026/01/30 | Posted on: 2026/02/01

I made the best memories.
I was able to experience the thin air environment.
The sunset, with nothing to obstruct it and higher than the clouds, was breathtaking‼️
The moon was too bright for stargazing, which was a bit disappointing, but I was thrilled to see so many satellites that I stopped counting them halfway through.

最高の思い出が出来ました。
空気が薄い環境を体感出来ました。
雲より高く何も妨げになるものがない中でのサンセットは感動‼️
月が明る過ぎて星空観察はチャッと残念でしたが、途中で数えるのをやめるくらいの人工衛星を見て感激しました。

The sunset and starry sky from the summit of Mauna Kea, which is higher than Mount Fuji, were amazing! My friend who went with me seemed to struggle with car sickness, but our guide, Sho-chan, was very kind and helpful, which I really appreciated. It was a tour I definitely want to join again!

Today, I went to the summit of Mauna Kea to watch the sunset. Originally, it was supposed to be an English tour, but the guide spoke Japanese as well, which made it very easy to understand the content. The summit is cold, but they provided outerwear for rent, so it was comfortable!

Tips and suggestions

It seems that some people experience not only altitude sickness but also motion sickness, so I think it's better for those who are sensitive to take medication before going.

高山病もそうですが、車酔いもする方がいるみたいで、弱い人は薬を飲んで行ったほうが良いと思います

The weather was perfect with no wind, and we had a truly happy time riding such cute and smart horses while enjoying the breathtaking views. Thanks to the guide's thoughtful care and gentle support, we felt safe and relaxed throughout the entire experience. My husband and I kept saying how much fun it was, and it truly became a wonderful memory for us. The woman who joined the tour with us was also very lovely, which made the atmosphere even nicer. This was one of the most unforgettable experiences of our trip to the Big Island. When we come back to Hawaii Island, we will definitely join again. If there were goods featuring the horse I rode or local items to support the ranch, I would have absolutely bought them. I would be so happy if you could create something like that. Thank you so much for such a wonderful experience!!

天気も最高で風もなく、素晴らしい景色の中で可愛くて賢いお馬さんに乗ることができ、本当に幸せな時間でした。ガイドさんの細やかな気遣いや優しいサポートのおかげで、終始安心して楽しむことができました。夫と「本当に楽しかったね」と何度も話すほど、心から素敵な思い出になりました。一緒に参加していた女性の方もとても素敵な方で、雰囲気もとても良く、ハワイ島旅行の中で忘れられない体験のひとつになりました。次にハワイ島に来た時も、絶対にまた参加したいです。自分が乗ったお馬さんのグッズや、牧場を応援できるローカルグッズがあったら必ず買っていたと思います。もし作っていただけたらとても嬉しいです。本当にありがとうございました!

I was unsure about joining the tour since I was going alone, but since it’s Hawaii Island, I decided to give it a try. This tour takes you to the summit in a 12-passenger bus. We go up to 4,200 meters, so to avoid altitude sickness, we take a 40-minute break at 2,700 meters to acclimatize. During that time, we could buy souvenirs and use the restroom, which was quite clean.

Once we reached the summit, it was very cold, around 0 degrees Celsius. Many people borrowed warm clothing, but I was fine with what I brought (a knit hat, neck warmer, fleece, down jacket, and thermal pants).

The sunset was amazing, as we could see it from a higher point than Mount Fuji. After that, we moved to a spot where we could see the starry sky, and while enjoying warm cocoa, we spent a luxurious time learning about which stars belonged to which constellations.

It’s a life-changing experience, so I highly recommend you go!

1人参加だしツアー行くか迷ってましたが、せっかくのハワイ島だから行ってみようと決めました。
こちらのツアーは12人乗りのバスで山頂までいきます。
4200mまであがるので、高山病にならないように2700m地点で40分休憩して体を慣らします。
そこではお土産を買えたりトイレも行けました。
トイレは普通に綺麗でした。

山頂まで行くととても寒くて0度くらいになります。
防寒具は借りてる人も多かったですが私は持参したもので足りました。
(ニット帽、ネックウォーマー、フリース、ダウン、浦起毛パンツ)

日の入りは富士山よりも高いところから見れてとても良いです。
その後、星空が見える位置まで移動し、どの星がどの星座か教えてもらいながら温かいココアをいただきながら贅沢な時間を過ごしました。

人生観が変わるのでぜひ行ってみてください!

It was an experience that could only be done on a tour! We had explanations on acclimatization to high altitudes, enjoyed BLT sandwiches, warm cocoa, and took lots of photos. I was thinking about not booking a tour and just seeing the starry sky on my own during the trip, but observing the stars from a place higher than the center was a really great experience.

ツアーじゃないとできない体験ばかりでした!
高地順応のポイント説明、BLTサンドに、温かいココアとたくさんの写真撮影。

The Mauna Kea at night has no lights and the rocky road is quite rough, so I think it's best to join a tour for a safe ascent!

It was a time to quietly watch the sunset sinking into the sea of clouds. The colors changed moment by moment. As I looked at the sky, I felt my mind gradually quieting down. It's beautiful. Even though I couldn't express more than that, it felt sufficient. A time when I didn't have to think about anything or be anyone. I thought it was incredibly luxurious to have moments like this when my heart could unwind.

雲海に沈んでいくサンセットを、ただ静かに眺める時間だった。刻々と色が変わっていく。空を見ているうちに頭の中がすっと静かになっていくのを感じた。きれいだね。以上の言葉が出てこないのにそれで充分だった気がする。何かを考えなくても、何者かでなくてもいい時間。こんなふうに心がほどける瞬間があるのはすごく贅沢だと思った。

Mahalo for joining us and for sharing your experience. We’re glad you enjoyed the tour and our team.

Just to clarify, our self-serve hot chocolate station is set up after the private group photos are taken to keep the tour flowing smoothly. We also want to note that we do not operate tours in unsafe weather, including snow. If conditions turn unfavorable, we always offer a full refund.

We hope you enjoyed the astronomer’s 90-minute star talk, the deep-space telescope images, and the photos captured by our astrophotographer.

I was nervous about the English tour, but our guide James was considerate and mixed in some Japanese. We were blessed with great weather and got to see the best sunset and starry sky! It was my first time seeing the Milky Way. I've participated in a Mauna Kea tour before, but this guide was great at taking creative photos. In the end, I wanted to give a tip, but I felt bad for not having any cash on me. I hope there will be a way to pay with a card in the future.

英語ツアーでドキドキでしたが、ガイドのジェームスさんは日本語を交えてくれたりして気遣ってくれました。お天気に恵まれて最高の夕日と星空が見られました!!
天の川を見たのは初めてです。以前もマウナケアツアーは参加したことがありますが、こちらのガイドさんは写真を工夫してとってくれたりして良かったです。

マウナケア山頂での夕日と満天の星空に感動
Activity Date: 2026/01/12 | Posted on: 2026/01/13

I couldn't find a Japanese tour, so I joined an English tour, which made me a bit anxious, but the result was absolutely satisfying! At one point, the road to the summit was closed due to thick fog, but as predicted by our guide James, the closure was lifted, and we were able to experience the best sunset and a sky full of stars at the summit of Mauna Kea.

Even though Hawaii is a tropical paradise, the temperature at the 4,000-meter summit was very low, around 0 degrees Celsius, and the air pressure was also low, which posed a risk of health issues. However, James was incredibly reliable, preparing and guiding us like a Sherpa, which was truly reassuring.

The beauty of the sunset through the Subaru Telescope and the starlit sky viewed from an even higher location than the Mauna Kea foothills is something I will never forget. James took some very skillful and creative photos, which I continue to enjoy even after returning home. Thank you very much!

日本語ツアーが見つけられず、英語ツアーでの参加となり、すこし不安でしたが結果は大満足でした!
一時は濃霧で山頂への道が閉鎖されてましたが、ガイドのJamesさんの予想通り、閉鎖が解除されマウナケア山頂で最高の夕日と満天の星空に出会えました。
常夏の​国ハワイとはいえ4,000m山頂は、気温が0度前後と非常に低く、気圧も低いことから、体調をくずすリスクがある中で、Jamesさんがシェルパのように頼もしく準備・案内してくれ、本当に心強かったです。
​すばる望遠鏡越しに沈む夕日や、マウナケア山麓より、さらに高い場所で見上げる星空は、一生忘れることができない美しさでした。
Jamesさんはとても上手でクリエイティブな写真を撮ってくれ、帰国後も楽しませてもらっています。

The meeting went smoothly, and we were able to comfortably move from Kona to the Onizuka Center at the mid-level. It was New Year's Eve, and although the clouds were thick and it had been raining since the day before, I was glad to see rare snow falling at the summit of Mauna Kea! The sunset was beautiful. The stargazing was a bit disappointing due to the clouds, but overall, I had a great experience participating in this tour.

I had a wonderful experience on the Mauna Kea tour. The trip was very well organized, and the whole experience was both smooth and memorable.

Our tour guide Jimms was excellent. He was friendly, professional, and very knowledgeable, and he explained everything clearly throughout the tour. He also made sure everyone felt comfortable and well taken care of, especially given the unique conditions at Mauna Kea.

This tour was truly unforgettable, and I would highly recommend it to anyone visiting the area. Thank you, Jimms, for such a great experience!

This tour is long but well worth it. We were picked up at the Starbucks, Queen’s Shopping Center, Waikoloa Beach Resort. We drove to the Mauna Kea Visitor’s Center where we had a very nice dinner. Next we went to the summit to view the telescopes and sunset from almost 14,000 feet. We the viewed the night sky through telescopes in almost complete darkness. Our driver and guide, Arthur, was fantastic. What a great experience!

During my stay on Oahu, I took a two-day, one-night trip to the Big Island and participated in this tour! I was impressed by the bilingual guide, Sho-yo, and I had a valuable experience learning about Hawaii's history and culture in such a short time. I was worried about the weather throughout, but I was able to enjoy the world's most beautiful sunset, and the explanation of the starry sky was wonderful! Thank you for making my year-end vacation so special!

The various stories shared by our guide, James, were enjoyable and very educational! Thank you so much.

山を登っていったとき、下界が雲に包まれているうえに出て、なんとも神秘的でした。天文台、日没、そして星空ととても充実したツアーでした。

ガイドのジェームズさんによる様々なお話が楽しくとても勉強になりました!本当にありがとうございました。

This was my second time participating, and I loved it just as much as last year! The two-hour horseback riding experience with the adorable horses is something you can't find in Japan. The hospitality of the staff was also wonderful, and I was very satisfied once again! I've been to the Big Island over ten times, but this experience is truly the best.

昨年に引き続き、大変気に入って2度目の参加でした!かわいい馬と一緒にたっぷり2時間の乗馬体験は日本では味わえません。スタッフの皆さんのホスピタリティも素晴らしく、今回も大満足でした!ハワイ島は10回以上来ていますが、この体験は本当に最高です。

There are places where you'll need to push through branches, so long pants are a must!

枝葉をかき分けて行く場所もあるので、長ズボンは必須です!

On the day of the tour, the weather in Kona was cloudy, which made me a bit worried, but it turned out to be no problem at all! The sunset was surrounded by a sea of clouds, creating a very magical atmosphere. For stargazing, even though the half-moon was out, I was able to see the Milky Way and winter constellations perfectly, making it a wonderfully romantic experience! Overall, the tour was smooth and efficient, and the guide was very kind, providing a comfortable experience.

当日コナは曇りで天気が心配でしたが、
全く問題にならなかったです!
サンセットは一面雲海で、とても幻想的でした。
星空観測も、半月が出ていましたが、天の川や冬の星座はばっちりと見れ、十分にロマンチックな体験でした!
また、全体を通してスムーズで無駄のないツアーで、ガイドもとても親切にしていただき、快適な体験ができました。

Sunset and Stars

What an amazing experience! We had the perfect weather conditions to watch an amazing sunset and an absolutely clear night to see the stars. BUT what made this trip unforgettable is James our tour guide. He is funny knowledgeable and kind. He made sure we were able to capture moments throughout our trip. He is an amazing photographer and was intentional in capturing our photos with the sunset and with the millions of stars! You have to book your trip with Hawaiian Eyes Tours.

Guide Show was friendly, and I was able to relax and enjoy the entire time. Not only did I learn about Mauna Kea, but I also gained insight into Hawaii's background and history, making it a very fulfilling experience. The sandwiches they prepared were delicious, and it was a memorable experience.

ガイドのショウさんが気さくで、終始リラックスして楽しめました。マウナケアだけでなく、ハワイの背景や歴史も学べてとても充実。用意してくれたサンドイッチも美味しく、心に残る体験でした。
